Abstract
The invention provides an aluminum and aluminum alloy welding backing, which comprises one or more welding backing blocks. Each welding backing block is made of, in percent, 10-23% of cryolite, 10-20% of sodium chloride, 5-10% of potassium chloride, 8-33% of boron oxide, 13-24% of silicon oxide, 10-15% of kaolin, 1-2% of chromium oxide, 3-10% of steatite and 6-18% of feldspar. The aluminum and aluminum alloy welding backing is low in melting point, liquid slag is high in surface tension, low in viscosity, fine in fluidity, not boiling and easy to rise and float on the surface of a molten pool, aluminum and aluminum alloy weld metal is guaranteed to be pure, and the weld appearance surface is guaranteed to be smooth, so that the aluminum and aluminum alloy weld metal becomes a fine weld in a forming slot at a time. Besides, welding procedures are reduced, welding materials are saved, welding production efficiency is improved, and weld quality is improved.
Description
Technical field
The invention belongs to the technical field of welding material in the Arc Welding Process, particularly the welding backing of aluminium and aluminium alloy single face welding two sides moulding welding method adapted.
Background technology
Development along with the aluminium alloy metallurgy industry; Be the made industry, being in particular shipping industry provides a large amount of aluminium and aluminium alloy stock, confession to build naval vessel hull such as luxury travel ship, high-speed craft, chemical tanker, aircraft carrier, high speed warship and its superstructure structure is used.For improving the welding production efficiency of ship construction, exploitation aluminium and aluminium alloy single face weld the welding method of two sides moulding, and the critical material of aluminium and aluminium alloy single face welding two sides moulding welding method is developed welding backing exactly.Liner is related to the act that can aluminium and aluminium alloy realize single welding, the conclusion of Zhejiang Province's technical information research institute science and technology novelty assessment report: do not see in the searching document and address.
Summary of the invention
Technical problem to be solved by this invention provides a kind of arc welding method that aluminium and aluminium alloy welding joint can carry out electric arc single face welding two sides moulding that solves; Reach the welding point weld seam and have good quality and the used welding backing of operative weldability ability; For this reason, the present invention adopts following technical scheme:
Said welding backing comprises one or more welding backing piece, and the prescription of said welding backing piece comprises following raw material: ice crystal, sodium chloride, potassium chloride, boron oxide, silica, kaolin, chromium oxide, talcum and feldspar, and said proportion of raw materials is: ice crystal 10 ~ 23%; Sodium chloride 10 ~ 20%, potassium chloride 5 ~ 10%, boron oxide 8 ~ 33%; Silica 13 ~ 24%, kaolin 10 ~ 15%, chromium oxide 1 ~ 2%; Talcum 3 ~ 10%, feldspar 6 ~ 18%.
Through above technical scheme; Fusing point of the present invention is lower; The molten slag surface tension is big, viscosity is little, good fluidity, do not seethe with excitement and slag be prone to rise and to float on weld pool surface; Guarantee aluminium and aluminium alloy weld seam metal is pure, the weld appearance smooth surface, make the weld metal of aluminium and aluminium alloy in forming tank, once become good weld seam.Reduce welding sequence, saved welding material, improved welding production efficiency, importantly improved weldquality.

The specific embodiment
Said welding backing comprises one or more welding backing piece, and the prescription of said welding backing piece comprises following raw material: ice crystal, sodium chloride, potassium chloride, boron oxide, silica, kaolin, chromium oxide, talcum and feldspar, and said proportion of raw materials is: ice crystal 10 ~ 23%; Sodium chloride 10 ~ 20%, potassium chloride 5 ~ 10%, boron oxide 8 ~ 33%; Silica 13 ~ 24%, kaolin 10 ~ 15%, chromium oxide 1 ~ 2%; Talcum 3 ~ 10%, feldspar 6 ~ 18%.
Because unique formula of the present invention, the color of formed spacer block is green or light green color, identification both attractive in appearance also easily.
The shape of cross section of said spacer block is the combination of rectangle 7 and trapezoidal 8, and the appearance of weld groove 4 of spacer block is located on the rectangle.This kind spacer block is different with common slim spacer block, and is more firm comparatively speaking, trapezoidal attractive in appearance, the material saving of bottom, and integral body is difficult for broken more.
Welding backing piece of the present invention is under the arc heat effect; Part generates unique and adapts to aluminium and the metallurgical required low-melting slag of aluminium alloy welding; Its protection deposite metal does not receive the invasion of harmful substance in the environment, holds welding pool, guarantees the single welding process of aluminium and aluminium alloy.
The fabrication schedule of welding backing piece of the present invention is to weigh up each part material powder in the ratio that above-mentioned prescription constitutes, and mixing, pugging, is pressed into base substrate, burns till the welding backing piece with high temperature behind the body drying.Subsequently, the spacer block that is up to the standards links to each other and to be connected into needed length and to be mounted on the aluminum foil tape.Through the qualified laggard storehouse of technical checking.
With reference to accompanying drawing, the present invention includes one or more welding backing piece 1, said spacer block 1 front is designed with welding fabrication groove 4 along longitudinal axis, and welding backing piece 1 can be by desired length, joins end to end to connect into a root bead and connect liner.On the longitudinal axis of appearance of weld groove, paint a centering red line 5, be convenient to be mounted on welding backing on the back side of welding point exactly.
After polylith welding backing piece 1 is connected to the length that needs; Stick together with aluminum foil tape 2; At first tear the separate paper 3 on the adhesive tape 2 during use off; Appearance of weld groove centering red line 5 on the polylith welding backing piece 1 is aimed at the welding point axis, and welding backing piece 1 closely joins with welding point, is mounted on the back side of welding point 6 then securely with aluminum foil tape 2.At this moment, can weld the effect that reaches the moulding simultaneously of single face welding two sides from the welding point front.
The slag that welding backing piece of the present invention is burnt till by welding arc, its molten slag surface tension is big, viscosity is little, good fluidity, do not seethe with excitement and slag be prone to rise and to float on weld pool surface, guarantees aluminium and aluminium alloy weld seam metal is pure, the weld appearance smooth surface.And the slag easy-clear of having on the weld metal.
Should be noted that at last; Above embodiment is only in order to explain technical scheme of the present invention; But not to the restriction of protection domain of the present invention, although with reference to preferred embodiment the present invention has been done explanation at length, those of ordinary skill in the art is to be understood that; Can make amendment or be equal to replacement technical scheme of the present invention, and not break away from the essence and the scope of technical scheme of the present invention.
